Don't be silly. What do you think Black IC is? This is a clear, obvious outgrowth of psychotropic IC - albeit in an uncontrolled manner. Each affected individual had interaction with a certain very few locations - locations which were chock full of server farms containing electronic sentients (to form a group to sum up AI, E-Ghosts, and Free Sprites) upon whom the electronic version of vivisection was being performed while they were alive and aware of it happening. This is exploratory surgery without anesthetic - and, in fact, making sure your patient is awake so they can feel all the pain, watch what's being done to them, and scream at the horror of it.
The spirit power of Possession/Inhabitation is far, far closer to what is actually happening. And 'revenge' seems to me to be the primary motivator there ...
